That IP address space is now owned by HP and this NTP host is now known as
usno.hpl.hp.com
Side note: the dec.com domain name was sold by HP and is now owned by Paul Kocher.
(He's one of the people that discovered the Spectre vulnerability in x86 CPU's.)
I've been in touch with Paul about dec.com and he told me that he's not interested
in selling it or passing it across to any related hobbyist group.
He advised me that he'd purchased it from HP when it was auctioned off.
According to the records, the domain dec.com was sold by Heritage Auctions on July 24th
2014 for $57,500.
In the same auction another person purchased digital.com for $373,750

FWIW, I own decnet.org and have for a couple of decades now. I had great plans for it
at one time, but I never got around to it. I'd be willing to let it go to a good
cause for considerably less :)

Getting time on TCP port 37 is /old/.? I only do it because that is all
I have until such time as I port something smarter. Note the following
from NIST: "We will continue to support the "TIME" protocol that uses
TCP port 37 for the forseeable future." So not responding on port 37
might not be a false negative, if only NTP is supported.

This is my fault. I checked that NTP was running on 204.123.2.72 and then just googled it
to find the name.
I found a hit on a page on ntp.org with the name usno.hpl.hp.com and just assumed it was
valid.
Turns out it has no name. This was a Stratum 1 server originally, but the page found by
google is not actively linked on the official ntp.org.list
This appears to have happened in more recent times. I can find references to it from 2019
where it appears it may have been in the process of being phased out.

Oh...? Well, what's a 'whoops' between hackers?? (the good olde
fashioned kind)
I went to the web page and, of course, understood the working solution
to put the 'disappeared' host names into the /etc/hosts.? That's a
standard thing to do on Windows and any Unix flavor I can think of.?
Personally, I think it is a win.? The one place where you /can't/ do it
as easily is on a PANDA Tops-20 distribution, which will check the
domain _first_ and wait for that resolve to time out before checking the
local hosts file (SYSTEM:HOSTS.TXT).
So that means you have to /wait/ for the time out, which, whatever
duration that happens to be is far too long for me.? It's quite
infuriating, actually. SYSTAT immediately knows, yet finger appears to
hang and mail delivery slows to a crawl.? You can't know how to
remediate unless you happen to be familiar with the source code.? Humph...
Avoiding the time out means you have to put whatever host you want into
the domain files, the format of which is both arcane and poorly
documented.? And then whack the resolver.? Now you have two files to
keep in sync.? That was one argument that I never won with MRC as having
it the other way around seemed to me to be easiest for everyone.
I finally edited my local copy of HSTNAM to not drive me crazy and also
gave DECnet hosts priority, which then turned up a gap in Tops-20.
HSTNAM /really/ wants the node number, even though the average user
can't do a blessed thing with it.? If it doesn't get a number, then
it...well, makes something up.? Of course, fixing all this broke
something else in MMAILR, which is another rabbit hole I have yet to get
myself out of.
This all being said, would the correct assumption be that HP is looking
to pull its Stratum-1 server or just cut down traffic?? I can't remember
where I read this, but apparently Stratum-1 servers get *a lot* of
traffic, so maybe HP didn't want to burn that bandwidth any more.?? Or...?

I already have four pairs of Swedish servers in my list - a pair each for a different

All the Netnod NTP nodes are two Servers with one of these FPGA things each,
the nodes have local CS cs clocks that are steered to UTC.
Time1 and Time100.Stupi.SE are at our clock lab and are directly driven from
the local timescale that is hydrogen maser and HROG-5 synthesizers to stear
time, frequency and phase.

Aweome.
In contrast have a $15 USB GPS dongle. ntpd on local Linux thinks it?s crap and syncs to
public servers.
The green LED on it flashes though, saying it is synced.

Don't you use GPS to do Cs clock verification? It used to be people would actually
carry those clocks around to do that, but I thought that procedure is obsolete now thanks
to GPS. It doesn't need to be done often given 10^-13 or so stability...

We report all clocks in Sweden that are at the different labs to BIPM as "RISE
Clocks",,
we have common view carrier phase, two-way communications satellite and two different
fiber transfer methods Stupi-Rise and carrier-phase/fiber to all the remote nodes.
(In common view GPS, you don't actually use the time from the GPS satellite, just
the signal.)
Stupi has a active hydrogen maser (1.5x10e-15 in 10,000sec) to drive one time scale
generator/phaser/stepper and
a cold-rubidium-atom thing (1.x10e-15 in 3 weeks) drive the second time-scale.

I have a grandfather clock in my hall that was made in 1740 by Mr R Wills of Truro.
It keeps pretty good time and announces the fact every hour.
Just sayin?

Perhaps I'm missing the point as to the relevance, but I am rather
jealous of you for that.

I have a clock on my wall that?s is exactly correct twice a day.

Ian,
How do you knew when to look at your clock (that is not moving) to make use of that
precise time?
